The Sierra Nevada snowpack, a major source of water supply in California, has reached its highest level since 1995, raising hopes for an end to the drought but also concerns about the possibility of flooding due to rapid melting.
Two people were rescued after a large sinkhole swallowed two cars in the Los Angeles neighborhood of Chatsworth as an unrelenting winter storm caused havoc in Southern California.
California is once again under threat as an energetic low pressure system quickly gathers strength off the West Coast, bringing with it heavy precipitation, thunderstorms and several feet of snow in the Sierra Nevada region. This, along with already saturated soils and high river levels, is expected to exacerbate ongoing flooding, prolong the risk of flash flooding, and mudslides, especially in recent burn scar regions. The National Weather Service has issued a warning for residents to be prepared, as the heavy rainfall, especially in southern California, is expected to be excessive today and tonight.
The continuous rounds of heavy rain on already saturated soils across California will likely lead to significant flooding, rapid river rises, mudslides, and flash floods or debris flows in burn scar areas. In addition, gusty winds may cause trees and power lines to fall. Travel in the mountains may also be hazardous due to heavy snowfall.
A major storm and atmospheric river are poised to impact California today and Thursday with heavy to excessive rainfall, flooding with debris flows and landslides near recent burn scar areas, heavy mountain snow and high winds.
